Jquery UI dialog not working in blogger blogspot

Jquery UI dialog not working in blogger blogspot

hi,

I am using blogger blogspot blog. I tried the the simple jQuery UI Dialog( http://api.jqueryui.com/dialog/) and it is not working.

Could it be because my blog is already using the followings-

<script src=' https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js' type='text/javascript'/>  
<script src=' https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js' type='text/javascript'/>

while the simple UI dialog box example is using, 

 

  

    <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
  

 

 

  

    <script src="//code.jquery.com/jquery-1.10.2.js"></script>
  

 

 

  

    <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

Is this the problem or is it something else? how can I solve the problem?

thanks!
